Catheterization was done on 13th August 2017 followed by which PSA was done first on 24th August. PSA score came out to be 15.90 ng/mL. Catheter was removed on 27th August but was reinstalled on the same day. On Sep 11th we re-performed the PSA test and PSA score came out to be 10.14 ng/mL. After that dad suffered from cough and cold on Sep 21st and he was on homeopathic medication. The PSA test was done on Sep 25 and cam out to be 36.41 ng/mL. Please suggest the next step.
